Estimates only. Not financial advice.
Lock-in-now is deterministic (0%). Plans that wait depend on future prices; risk is near-zero when inventory comfortably exceeds the goal. Volatility: each stack's option-implied vol if a ticker is set, otherwise 30%. Lognormal model; real markets have fatter tails.

- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

This calculator builds the minimum-tax sell schedule across your lots, accounting for federal long-term capital gains, the net investment income tax, and your state.

State Street equity questions
- How much STT stock do I sell to fund a goal without overpaying tax?
- It depends on your cost basis, your target amount and date, and how the sale spreads across tax years. Selling vested STT shares triggers long-term capital-gains tax, plus the 3.8% net investment income tax and state tax above certain income, and bunching a large sale into one year can push the gain into a higher bracket. The calculator above builds the minimum-tax sell schedule across your lots to net your target amount by your date.
- Does State Street grant ISOs, NSOs, or RSUs?
- Equity compensation at State Street typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do State Street RSUs use double-trigger vesting?
- No. State Street restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
